Description of Change
ADEPT™ technology is a set of electronic features including SmartTorque2 and SmartCoast™,
and Predictive Gear Shifting.
SmartTorque2 senses the selected gear, road grade, and overall engine load. As these conditions
vary, SmartTorque2 determines the exact amount of torque required to maintain road speed and
eliminate unnecessary downshifts.
SmartCoast™ has been added to improve the efficiency of coasting events. SmartCoast™ will
disengage the driveline on moderate downhill grades or when the operator lifts off the accelerator
pedal, allowing the engine to return to idle.
Predictive Gear Shifting improves vehicle speed tracking performance during cruise control. The
feature will utilize vehicle characteristics and road grade profile information to determine the proper
transmission gear when the engine is power limited on hills.
Predictive Engine Braking aims to enhance the vehicle speed limiting capability of existing engine
brake features based on the upcoming road grade. The features to which this predictive
functionality can apply are Cruise Control and Engine Brake Interaction or Maximum Vehicle
Speed Control.
On-ramp Boost is a performance feature that improves vehicle acceleration on an on-ramp leading
to an interstate which increases the merging speeds and assists in an easier merging maneuver. It
allows the vehicle to operate in a fuel-efficient mode during regular operation and allows better

performance during critical situations.
Predictive Road Speed Governor improves efficiency of the vehicle by adjusting the Road Speed
Governor within programmable offsets based on current and upcoming road grade.
Dynamic Power aims to improve overall engine efficiency by limiting use of excessive torque when
it is not required. Utilizing similar references as SmartTorque2, Dynamic Power modulates
available engine torque to reflect current vehicle operation & environmental influence.

Note : Predictive Gear Shifting, Predictive Engine Braking, On-ramp Boost, Dynamic
Power, and Predictive Road Speed Governor require either a Cummins® Route
Parameter Manager (RPM) or an OEM Predictive Cruise Control module to get lookahead road information.
Reason for Change
Fuel economy and performance improvement option
Service Instructions
Electronic Tools Required:
INSITE™ Pro electronic service tool for engine calibration update
ServiceRanger™ 4 for transmission software update (if required)
1. Check engine, transmission, and adaptive cruise control system compatibility. See Product
Affected Table, Table 1, Table 2, and Table 3 for applicability.
2. Review ADEPT™ technology documentation on cumminsengines.com and communicate
modification charge to customer.
The customer will incur a fleet count charge as well as the stated modification charge.
3. Verify that transmission software meets minimum software requirement. See Table 4 below.

If necessary, update the transmission using the Eaton™ ServiceRanger™ 4 service tool.
If minimum transmission software requirement is not met, ADEPT™ features will not function
properly and fault codes can be triggered.
If a feature is enabled that the transmission does not support, fault code 5297 will come
active as a result.
4. Update the engine calibration to ADEPT™ technology calibration using selection matrix in Table
5 below. See the ISX15 CM2350 X101 Service Manual, Bulletin 4310641. Refer to Procedure 019032 (/qs3/pubsys2/xml/en/procedures/105/105-019-032.html) in section 19. See the X15 CM2350
X114B - Efficiency Series Service Manual, Bulletin 5411181. Refer to Procedure 019-032
(/qs3/pubsys2/xml/en/procedures/105/105-019-032.html) in section 19. See the X15 CM2450
X124B Service Manual, Bulletin 5504583. Refer to Procedure 019-032
(/qs3/pubsys2/xml/en/procedures/105/105-019-032.html)in Section 19.

Note : Dynamic Power is available only for X15 CM2450 X124B engine ratings that
have ECM calibration codes starting with 'KW' located in Table 5 in the ADEPT™
Technology ECM Calibration Code column.
5. Clear resulting fault codes
Depending on the download sequence an inactive fault code 5297 can be logged in the ECM
after the upgrade as a result of transmission and ECM communication loss during calibration
event.
6. Verify ADEPT™ features are turned on in the ECM. Under the Features and Parameters section
in INSITE™ electronic service tool:
For Ultrashift® or Advantage® Transmissions:
Adjust “SmartCoast” to “Enabled” if set to “Disabled” (May be located in the Cruise Control
section or as a separate featured called SmartCoast). The Advantage or Ultrashift
transmissions only support Smart Coast in cruise control.
The Smart Coast features may not be restored after a calibration has taken place using
a vehicle electronics programming station (VEPS) machine. Use INSITE™ electronic
service tool to connect to the ECM and follow the instructions in Step 6 to confirm that
the parameter Smart Coast is set to Enabled.
Adjust “Load Based Torque Control” to “Smart Torque 2” if set to “Base”.

Adjust “Road Speed Governor Type” from “Traditional” to “Predictive”. If Predictive Road
Speed Governor is unavailable in the calibration, “Road Speed Governor Type” will be Read
Only.
For Endurant™ Transmissions:
Adjust “SmartCoast” to “Enabled” if set to “Disabled” (May be located in the Cruise Control
section or as a separate feature called SmartCoast). The Endurant transmission supports
Smart Coast in accelerator control, cruise control, or cruise and accelerator control.
If available, set the “Operating Mode” to the desired option (select “Both” for maximum
coasting opportunity).
The Smart Coast features may not be restored after a calibration has taken place using
a vehicle electronics programming station (VEPS) machine. Use INSITE™ electronic
service tool to connect to the ECM and follow the instructions in Step 6 to confirm that
the parameter Smart Coast is set to Enabled.
For CM2450 (ECM calibration code starting with 'KW' located in Table 5 in the Existing ECM
Calibration Code column) and CM2350 ECMs, Adjust “Load Based Torque Control” to “Smart
Torque 2” if set to “Base”.
For CM2450 ECMs with ECM calibration code starting with 'KW' located in Table 5 in the
ADEPT™ Technology ECM Calibration Code column, adjust "Load Based Torque
Control" to "Dynamic Power" if set to "Base".
Adjust “Predictive Gear Shifting” to “Enabled” if set to “Disabled”.
Adjust “Predictive Engine Braking” to “Enabled” if it is set to “Disabled”.
Adjust “On-ramp Boost” to “Enabled” if it is set to “Disabled”.
Adjust “Road Speed Governor Type” from “Traditional” to “Predictive”. If Predictive Road
Speed Governor is unavailable in the calibration, “Road Speed Governor Type” will be Read
Only.

Note : Predictive Gear Shifting, Predictive Engine Braking, On-ramp Boost, Dynamic
Power, and Predictive Road Speed Governor features are only applicable if the vehicle
has a Cummins® Route Parameter Manager or OEM predictive cruise control system.
7. Set upper and lower cruise control droops to customer desired settings.
Default settings are 3 miles per hour (mph) upper and 6 mph lower.
The Cruise Control Lower Droop controls the range of cruise control based SmartCoast™.
SmartCoast™ will not function with a 0 mph Cruise Control Lower Droop. Maximum fuel
economy is achieved using 6 mph, and a minimum of 3 mph is recommended.
8. Set Road Speed Control maximum speed to customer desired settings.
The RSG Maximum Vehicle Speed sets the maximum coasting speed for Accelerator Control
operating mode. A minimum of 3 mph greater than maximum Accelerator Vehicle Speed is
recommended.
If the Maximum Vehicle Speed Control feature is used, the start braking speed will also set the
maximum coasting speed. A start braking speed that is a minimum of 3 mph greater than
Maximum Accelerator Speed is recommended.

9. Adjust the Predictive Road Speed Governor Maximum Positive and Maximum Negative Offsets
to customer desired settings.
Default and recommended settings are 3 miles per hour (mph) for both. Input both as positive
values.
“Road Speed Governor Type” must be set to “Predictive” for the maximum offsets to be
visible.
10. If any fault codes or symptoms remain, reference the standard troubleshooting procedures. If
Fault Code 5297 is active, review the transmission type and features in Table 4 above to determine
what was incorrectly enabled.
